* Note that as provided from the factory, the universal data transceiver is set to the RS-232 point-to-point
(200 kbps) and low speed modes of operation. In the low speed mode the unit will operate with all duty
cycles including DC (logic 0 or logic 1 continuously). In the high speed mode of operation, the system will
operate properly with all duty cycles from 50-50% to 70-30%.
General Information
The Universal Data Transceiver is fully compatible with EIA standards for RS-232, RS-422 and
RS-485 at data rates from 0 (DC) to 2.1 mbps (200 kbps for RS-232) in the low speed mode
or from 10 kbps to 10 mbps in the high speed mode. It may be used for simplex or full
duplex asynchronous transmissions in both point-to-point systems and drop-and-repeat
data networks. It may also be used as a protocol converter. Although there are no operating
controls, the user must congure the unit for the protocol, speed and mode of operation
desired.
The universal data transceiver comes in two versions, the 5012 stand-alone model and the
5018A card-cage model. The two models are fully compatible with each other.

Fiberlink® 5012
Operation Theory
Theory of Operation
The transmitting section of the universal data transceiver converts an incoming RS-232,
RS-422 or RS-485 signals into pulses of light at the transmitting LED located in the “Transmit
(or Tx)” optical connector on the unit. These pulses of light equate to ON for a positive input
level and OFF for a negative or zero input level.
The receiving section of the universal data transceiver produces a user selectable RS-232,
RS-422 or RS-485 compatible output from the received light at the photodiode located in
the “Receive (or Rx)” optical connector on the unit. Due to the fact that all internal logic
signals are converted to either light-on or light-o, any protocol may be used in conjunction with any other protocol, thereby allowing the transceiver to be used as a data
converter as well as a general data transceiver. In addition, provision is incorporated to
allow drop and repeat operation with any protocol.
During normal operation, the RTS line (terminal block position 6) is not used. In external
RTS operation (for RS-485), terminal block position 6 is used as an enable input to toggle
the unit between transmit and receive. In this mode a positive input switches the unit to
the transmit mode while a zero input switches the unit to the receive mode. As an alternative, the unit may be automatically switched from transmit to receive by means of an
internal data-driven timer (Data-Derived T/R switching).

Optical Fiber
Versions of the universal data transceiver are available to drive most multimode (MM) and
single-mode (SM) optical bers. The specic models are identied by a sux at the end of
the model numbers as follows:
Fiber Size Connector 850nm 1310nm
50µ, 62.5µ MM ST -1 -3
8/10µ SM FCPC N/A -7
A 6300 adapter is available to allow the -1 and -3 versions of the 5012 model to be used
with multimode ber and SMA connectors. A 6310 adapter is available to allow
the -7 versions of these models to be used with single-mode ber and single-mode
ST connectors.
Indicator LEDs
The 5012 model has three green signal indicator LEDs that continuously monitor operation.
One, labeled “Power (or PWR)”, lights when operating power is present. The other two,
labeled “Transmit (or Tx)” and “Receive (or Rx)”, turn on whenever the transmitted or
received data is in the “high” state and o when it is in the “low” state. As a result, they
actually blink at the rate of the operating data. However, most data rates are so fast that
these LEDs will usually appear to be on continuously.

Conguring a ring or loop-type data bus
In addition to point-to-point transmissions, the universal data transceiver can be used to
implement a ring or loop-type data bus. This is accomplished by setting the internal DIP
switches as shown in the following diagram.
When the universal data transceiver is used in this mode, any location can receive or insert
data into the ring/loop but only one station at a time is permitted to insert data. All other
stations will receive the data but must maintain their individual input lines in the low state
(RS-232, terminal block position 2 negative with respect to position 1; RS-422, terminal
block position 2, negative with respect to position 3) to prevent loop lock-up. RS-485
operation does not have the above restriction due to the fact that it is in the tri-state mode
when not transmitting.
Note that the rst (or host) location is set to the point-to-point mode. All other locations are
set to the drop-and-repeat mode. This is to prevent loop lock-up or data “echos”.

Operating considerations for ber optic cable
The universal data transceiver may be supplied with ST or FCPC type optical connectors
and will operate with most common ber optic cables. However, it is important to use the
correct type of ber optic cable as required by your particular transceiver model. Some
models (ending in -1 and -3) are designed for use at 850 nm, while others (ending in -7)
function at 1310 nm.
When using any type of ber optic cable, be careful not to cause excessive strains, especially at the cable-to-connector junctions. Also, do not subject the cable to sharp bends or pull
it around sharp corners. Whenever possible, service loops or extra slack should be provided
in any installation. While excessive precautions are not necessary, ber optic cable should
be treated with moderate care as it does contain thin, fragile strands of glass.
Notes Regarding Fiber Optic Cable
Multimode ber optic cable contains an optical ber with a light carrying “core” that is only
.0025 inches (62.5µ) diameter. Single-mode ber optic cable has an even smaller “core”, only
00032 to .0004 inches (8-10µ). This is smaller than a human hair! Any minute particle of dirt
or dust can easily block this ber from accepting or radiating light. As a result, the key word
is cleanliness. Always use the dust caps provided with all optical connectors whenever they
are exposed to air. Also, it is a good idea to gently clean the tip of an optical connector with
alcohol whenever dust is suspected.
Mechanical butt splices or optical feedthroughs must be installed properly. Multimode
devices will not operate properly with single-mode devices even though they may look the
same. Using the wrong device can easily add more attenuation than specied, resulting in
impaired performance.
Operating Pointers
Remember to check attenuation of the ber optic cable. The system will only operate
properly if these specications fall within the range of the system’s loss budget.

Page 19Fiberlink® 5012 User’s Manual
Fiberlink® 5012
Troubleshooting
If your system is not operating properly, the following checklist may help to diagnose the
problem:
A. Check Transmitter or Transmit Section of a Transceiver
1. Is operating power (DC, AC, Voltages) correct?
2. Are you using the correct pins on the connector or terminal block?
3. Is the correct signal level present at transmitter input?
4. Is the optical connector on the transmitting LED clear of any
obstruction or minute dirt particles?
5. Is there a short circuit anywhere in the system due to common
power ground, signal ground and case?
B. Check Optical Connectors
1. Are the connectors the correct size for the ber?
2. Are the ends of the connectors free of all dust or dirt? If not, gently
clean the tip of the connector with a clean cloth or gauze moistened
with alcohol.
3. Is the ber broken in the connector? A quick inspection with an
inexpensive jeweler’s loop can determine this.
4. Is the ber protruding from the tip of the connector? If so,
renishing will be necessary.
C. Check Fiber Optic Cable
1. Is the ber optic cable pulled too tightly around a sharp corner?
2. Is the correct ber size being used with the correct transmitter/
receiver combination?
3. Does the ber pass light at all? A small penlight or ashlight can
usually be used for this test.
4. Does the ber have too much attenuation for the system? The
attenuation measured on the installed cable will always be dierent
than when the cable was still on the reel.
5. When using lengths shorter than 10 meters (30 feet), overloading of
the receiver may occur. The shorter the length of the ber, the
greater the possibility for this condition. Be sure there is adequate
attenuation in any system. For very short distances, contact the
factory for assistance.
D. Check Receiver or Receiving Section of a Transceiver
Follow the same steps as for checking the Transmitter.
